Answer:
Option D.
Explanation:
The above answer given is incorrect. Nucleotides consist of a phosphate group attached to a pentose sugar, with 5 carbons, (deoxyribose sugar in the case of DNA) and the pentose sugar is also attached to a nitrogenous base. DNA is incorrect as nucleotides are the building block of DNA hence DNA is NOT a component of nucleotides.
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.
